Struct Point3 

pub struct Point3 {
    pub x: f64,
    pub y: f64,
    pub z: f64,
}

A 3D point in Cartesian space (angstroms).

Fields

x: f64

y: f64

z: f64

Implementations

impl Point3

pub fn new(x: f64, y: f64, z: f64) -> Self

Create a new point.

pub fn zero() -> Self

The origin (0, 0, 0).

pub fn distance(&self, other: &Self) -> f64

Euclidean distance to another point.

pub fn add(&self, other: &Self) -> Self

Component-wise addition.

pub fn sub(&self, other: &Self) -> Self

Component-wise subtraction.

pub fn scale(&self, s: f64) -> Self

Scalar multiplication.

pub fn dot(&self, other: &Self) -> f64

Dot product.

pub fn cross(&self, other: &Self) -> Self

Cross product.

pub fn norm(&self) -> f64

Euclidean norm (length).

pub fn normalize(&self) -> Self

Normalize to a unit vector.

Panics

Panics if the vector has zero length.

pub fn try_normalize(&self) -> Option<Self>

Try to normalize to a unit vector, returning None if the vector has zero length.

Trait Implementations

impl Clone for Point3

fn clone(&self) -> Point3

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Point3

impl Debug for Point3

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Point3

fn eq(&self, other: &Point3) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
